Re: [las_users] Experts kindly help -- installation and configuration setting for Live access server

If you did not originally start the server using the $LAS_HOME/startserver.sh script then there will not be a $CATALINA_PID file created and the $LAS_HOME/stopserver.sh script won't work as you have just discovered.

Just to to $TOMCAT_HOME/bin and run shutdown.sh instead.

Yes, I could about solve mysql database permission problem and ant building problem, but when I try  to restart server I am getting this problem, I tried deleting PID in tomcat folder also

Using CATALINA_BASE:   /usr/local/www/html/TOMCAT_DEMO/tomcat
Using CATALINA_HOME:   /usr/local/www/html/TOMCAT_DEMO/tomcat
Using CATALINA_TMPDIR: /usr/local/www/html/TOMCAT_DEMO/tomcat/temp
Using JRE_HOME:        /usr/lib/jvm/jdk1.7.0_09
Using CLASSPATH:       /usr/local/www/html/TOMCAT_DEMO/tomcat/bin/bootstrap.jar:/usr/local/www/html/TOMCAT_DEMO/tomcat/bin/tomcat-juli.jar
Using CATALINA_PID:    /usr/local/www/html/TOMCAT_DEMO/tomcat/webapps/UI_PID
$CATALINA_PID was set but the specified file does not exist. Is Tomcat running? Stop aborted.

As per the ferret documentation I have installed live access server, these are the details of installation

hostname = las
Fully qualified domain name (FQDN) = las.nio.org
port 8080 both for tomcat and http server

I have provided tomcat full domain name as las.nio.org and http proxy full domain name as las.nio.org:8080. For this I got interface as http://las.nio.org.8080/las

product server detail


when I try to see the plot I am getting this error, even though mysql containing database name LAS_insitu_demo and tables.

Unfortunately, we cannot provide what you have asked for.
Database access failed: SELECT Latitude, Longitude, t, Salinity,Salinity FROM Indian WHERE (Salinity<-999.0001 OR Salinity>-998.9999) AND (Salinity<-999.0001 OR Salinity>-998.9999) AND ((Longitude>=20.0) AND (Longitude<=40.0)) AND ((Latitude>=-75) AND (Latitude<=30)) AND ((Depth>=0) AND (Depth<=6500)) AND ((t>=19771207) AND (t<=19891223))

This is most likely because the database access parameters in this file: $TOCMAT_HOME/webapps/las/WEB-INF/classes/resources/database/DatabaseBackendConfig.xml are not set up correctly to access the database.  Details for setting this up are provided here: http://ferret.pmel.noaa.gov/LAS/documentation/installer-documentation/adding-scattered-data/using-a-database/configuring-the-las-database-service/

So my questions are

1. How do I modify the LAS page details like, company logo, about us, contact us,which file I need to modify and how to run modified file in order to have change in LAS page preview.

The contact information and such is collected in the configuration script, but you can modify the look and feel of the home page by editing the files template files for the header, body and footer of the page.  See $LAS_HOME/WebContent/productserver/templates/V7UI*

2.How do I put data into LAS ,whether its possible without using mysql database, I mean if I keep netcdf files in directory /las/data whether it works ?

3. I didn't understand about apache ant compilation and execution process.

The ant process is similar to running make for C programs. It will compile the code and build the war file needed to run the server.  Then it will copy it to the right location in your $TOMCAT_HOME directory.  Once the new war file is in place you can run the stopserver.sh and startserver.sh scripts to get the new server configuration running.

experts kindly help with examples if possible, because I am new to this server installation.

There are many examples including details about how to redeploy the server here: 


Thanks in advance,
